The part number **02015J8R2ABSTR** refers to a high-precision, thin-film Surface Mount Device (SMD) capacitor, typically manufactured by **AVX (Kyocera AVX)**. This specific component is part of the **Accu-P®** series, designed for high-frequency RF (Radio Frequency) and microwave applications. --- ### 1. Part Number Breakdown Understanding the alphanumeric code helps identify the technical specifications: | Code Segment | Feature | Description | | :--- | :--- | :--- | | **0201** | Case Size | 0.6mm x 0.3mm (extremely small) | | **5** | Voltage | Rated for 50 Volts | | **J** | Dielectric | Accu-P (Thin Film Technology) | | **8R2** | Capacitance | 8.2 pF (Picofarads) | | **A** | Tolerance | ±0.05 pF (Ultra-tight tolerance) | | **B** | Termination | Nickel/Solder (Standard) | | **STR** | Packaging | Tape & Reel | --- ### 2. Key Technical Specifications This component is engineered for precision rather than bulk energy storage. * **Capacitance:** 8.2 pF * **Voltage Rating:** 50V DC * **Tolerance:** ±0.05 pF (This is exceptionally precise, crucial for tuning circuits). * **Operating Temperature:** -55°C to +125°C. * **Q-Factor:** High Q (Low loss) at Gigahertz frequencies. * **ESR (Equivalent Series Resistance):** Very low, making it ideal for signal integrity. --- ### 3. Core Technology: Thin Film (Accu-P) Unlike standard Multilayer Ceramic Capacitors (MLCCs), the **02015J8R2ABSTR** uses **Thin-Film Technology**. 1. **Precision:** Physical dimensions and electrode placement are controlled via photolithography, similar to integrated circuit manufacturing. 2. **Stability:** It offers very low SRF (Self-Resonant Frequency) shift and maintains stable capacitance across wide frequency ranges. 3. **Performance:** It minimizes parasitic inductance, which is vital for circuits operating in the 2.4GHz to 10GHz+ range. --- ### 4. Typical Applications Due to its small size and high precision, this part is found in: * **Mobile Devices:** Smartphones, Wi-Fi modules, and Bluetooth transceivers. * **Satellite Communications:** LNA (Low Noise Amplifiers) and power amplifiers. * **RF Filters:** Bandpass and high-pass filters where exact values are required for frequency selection. * **VCOs:** Voltage Controlled Oscillators for frequency stability. --- ### 5. Handling and Soldering * **Size:** Because 0201 components are the size of a grain of salt, they require automated SMT (Surface Mount Technology) assembly and high-resolution optical inspection. * **Soldering:** Reflow soldering is recommended. Hand soldering is extremely difficult and usually discouraged for this case size.
